dt-bindings: phy: bindings document for common Broadcom SATA3 PHY driver

This patch:
1. Renames DT bindings document of Broadcom STB SATA3 PHY driver to
common Broadcom SATA3 PHY driver bindings document
2. Adds bindings info for NS2 SATA3 PHY

-* Broadcom SATA3 PHY for STB
-
-Required properties:
-- compatible: should be one or more of
-     "brcm,bcm7425-sata-phy"
-     "brcm,bcm7445-sata-phy"
-     "brcm,phy-sata3"
-- address-cells: should be 1
-- size-cells: should be 0
-- reg: register range for the PHY PCB interface
-- reg-names: should be "phy"
-
-Sub-nodes:
-  Each port's PHY should be represented as a sub-node.
-
-Sub-nodes required properties:
-- reg: the PHY number
-- phy-cells: generic PHY binding; must be 0
-Optional:
-- brcm,enable-ssc: use spread spectrum clocking (SSC) on this port
-
-
-Example:
-
-       sata-phy@f0458100 {
-               compatible = "brcm,bcm7445-sata-phy", "brcm,phy-sata3";
-               reg = <0xf0458100 0x1e00>, <0xf045804c 0x10>;
-               reg-names = "phy";
-               #address-cells = <1>;
-               #size-cells = <0>;
-
-               sata-phy@0 {
-                       reg = <0>;
-                       #phy-cells = <0>;
-               };

-               sata-phy@1 {
-                       reg = <1>;

-               };
-       };

+- reg: register ranges for the PHY PCB interface
+- reg-names: should be "phy" and "phy-ctrl"
